People were asking about the Packout a few pages back and I can at least give my review on it. I've had it for about 6 months and absolutely LOVE this thing. For me, it's the perfect setup. My 8-5 is a desk job but I flip houses on the side. I don't want to leave all of my tools at the flip house and I don't want or can afford a trailer, and I don't want all my tools floating around in my truck and in the bed. I think I paid close to $300 for my base with wheels, the mid size packout and then one of them with the clear lids and small compartments that I have filled with different types of screws.
I wouldn't say I have all of the boxes completely packed down, but they are all full for sure. I'm in decent shape, 31 years old and 6' foot and I can barely pick up the whole unit and get it in the back of the truck. If it was any heavier, I would need to separate the unit into sections. I am able to keep it in my truck and unload everything all at once in one trip into the flip house. I have to go up and over about 6 concrete steps once out of the truck and into the house and so far, everything has held up including the handle. Everyone asked/complained about the little bar at the bottom/front of the rolling box and I think it's purpose is a hooking point so you can rest stuff on top of the packout and run a bungee cord down to it and hook on. I've used it that way 4 or 5 times and it's perfect.
I do contract some work out and every one of guys who see me working out of the packout ask about it and rave how awesome it is. I have it pretty well organized so for me it's super efficient and exactly what I needed.
It's gotten rained on as well once and everything inside was still nice and dry. Let me know if you have any specific questions on it. For me, it's the perfect setup.
